Embodiment Construction

[0028] The present invention uses nitrogen as the fluidizing gas to transport the aluminum powder to the detonation engine, and at the same time, quantitatively transports oxygen and hydrogen to the detonation engine through the delivery system. In order to realize the precise delivery of aluminum powder, oxygen and hydrogen, different way of delivery. For aluminum powder, nitrogen is used as the fluidizing gas and the conveying method is driven by a motor. The precise delivery of oxygen and hydrogen can be controlled by a pressure reducing valve and a solenoid valve. Sensors with different functions are placed in the precise control system for real-time monitoring. The detonation engine consists of a pre-explosion tube, a mixing tube, a spiral tube, a test tube and a nozzle, and the parts are connected by flange bolts.

[0029] In order to make the purpose, features and advantages of the technical solution proposed by the present invention more obvious and understandable, t...

Abstract

The invention relates to the technical field of engines, in particular to a powder detonation engine conveying system. Comprising a pipeline 1, a pipeline 2, a pipeline 3 and a pipeline 4, the pipeline 1 and the pipeline 2 share a set of nitrogen source, the pipeline 1 is used for conveying metal aluminum powder, the pipeline 2 is used for purging the whole system after a test, and the pipeline 3 and the pipeline 4 are respectively used for conveying oxygen and hydrogen. In order to ensure the conveying accuracy and time sequence control of hydrogen, oxygen and metal aluminum powder, a flow meter, a pressure transmitter, an electromagnetic valve and other elements are installed on a conveying pipeline, and the pressure intensity of the front end is adjusted through a pressure reducing valve to achieve adjustment of the conveying flow. According to the invention, detonation waves are formed by mixing powder with oxygen and hydrogen, so that thrust is generated, the formed detonation waves are stronger theoretically, the generated thrust is larger, and engineering application is easier to realize.

Description

technical field [0001] The invention relates to the technical field of engines, in particular to a delivery system and method for a powder detonation engine. Background technique [0002] Detonation is a strong coupling of leading shock wave and chemical reaction, self-sustained propagation and strong intermittent combustion phenomenon, accompanied by a large amount of energy release. The leading shock wave is similar to a pneumatic piston, which pre-compresses the reactants in front of the wave to increase the temperature and pressure rapidly, so the reactants can undergo violent chemical reactions on a small scale and release a large amount of chemical reaction energy. This energy is used to support the shock compression of the front reactants by the leading shock wave. Therefore, the detonation wave can sustain itself without attenuation. The detonation process is not only a hydrodynamic process, it also contains complex chemical reaction kinetics, and the two interact....
